Midea Cube 20 Pint Review: A Small Dehumidifier with a Big Bucket
Midea's Cube 20 brings the nesting cube design and an extra-large bucket to a small 1,500 sq ft unit.
By Daniel Brooks
Updated October 24, 2026
The Midea Cube 20 Pint Dehumidifier is rated at 20 pints a day under the current DOE test and covers up to 1,500 sq ft, with Midea’s nesting cube design and a bucket up to 3X larger than usual. It is our top pick among small portable compressor dehumidifiers.
Our Verdict
The Cube 20 is the small dehumidifier we recommend for bedrooms, bathrooms and small basements. Its DOE rating is realistic, the large bucket means fewer trips to the sink, and Wi-Fi, voice control, auto restart and auto defrost are included.
It is pricey for its capacity, and the cube is wide for a small unit.

Design
Lift and twist to extend the Cube for use, then nest it down to store. The bucket holds up to 3X more than a conventional unit.
A drain hose lets it drain continuously into a sink or floor drain.
Controls
The SmartHome app, Alexa and Google control it from anywhere, with humidity adjustable from 35% to 85%.
Auto restart and auto defrost protect it through power cuts and cool nights.
Placement Tips
Set the dehumidifier in the dampest part of the space, a few inches from walls and furniture so air can flow in and out. Close windows and doors while it runs so it is not drying the outdoors.
In a basement, a central spot works better than a corner, and a level floor keeps the bucket and pump working properly.
Running Costs and Care
Set the humidistat to around 45% to 50% so the compressor cycles off once the space is dry, which keeps power use down.
Rinse the filter every couple of weeks during heavy use, and check the bucket and hose for buildup. A clean unit removes more water.
How It Compares
Against Midea’s standard 22 pint, the Cube 20 holds far more water and nests for storage.
Against Frigidaire’s 22 pint Wi-Fi model, the Midea has a bigger bucket, while the Frigidaire is slimmer.
